Isn't the fresnel function the same thing as a falloff texture?

no it is not the same. Fresnell is dependant on the the IOR value. With falloff you can assign two colors and use a blend curve to control between the two.

For example, if you want an objects color to be dependant on the viewing angle, you need a falloff type texture to get control over the behavior.

A falloff should be a very simple addition to our procedural textures
